Method Detail

readVectorFile

protected void readVectorFile(java.lang.String arffFileName,
                              boolean sparse)

Description copied from class: SOMLibSparseInputData

Reads the input data from the given file, which has to follow the Input Vector File specification. Additionally calculates the AbstractSOMLibSparseInputData.meanVector and creates the AbstractSOMLibSparseInputData.nameCache for faster index search.

Overrides:

readVectorFile in class ARFFFormatInputData

Parameters:

arffFileName - the name of the input vector file.

getInstanceName

protected java.lang.String getInstanceName(java.lang.String line,
                                           java.io.BufferedReader reader)
                                    throws java.io.IOException

Throws:

java.io.IOException

getFormatName

public static java.lang.String getFormatName()

main

public static void main(java.lang.String[] args)

getClassAttributeName

protected java.lang.String getClassAttributeName()

Overrides:

getClassAttributeName in class ARFFFormatInputData
